Recently I added an Atari 1200XL to my collection. This is a modified one and has multiple OS installed so at the press of a button it can be any of the 8 Bit line. It has also had modifications to make the video clearer and fix the SIO limitation of the machine. It's a pity the 1200XL was a flop (mainly due to compatibility issues I believe) The actually build quality of the machine is fantastic and the keyboard is the best I have ever used on an Atari 8-Bit
